Strings coming from CL programs are not null terminated unless you specifically 
do it in the CL program.
I wrote a function which extracts the fixed length string from argv[x], trims 
trailing blanks, and puts in the null terminator.

Subject: [C400-L] Help Calling a C program From CL


I have written a simple C program:

#include <stdio.h>
#include <stdlib.h>


int main( int argc, char *argv[] )
{
        char *rc = NULL;

        if (argc != 2)
        {
                fprintf( stderr, "Need to pass a parameter\n" );
                exit( 1 );
        }

        rc = getenv( argv[1] );
        if( rc == NULL )
        {
                exit( 1 );
        }
        else
        {
                printf( "%s", rc );
                exit( 0 );
        }
        
}


This works perfectly fine when it is called using qsh.

How can this be called from CL ?
Would this code need to be changed to integrate with CL ?

-Thanks
